BATTERY TERMINAL Filed Dec. 10, 1936 Patented Nov. s, 1933 UNITED STATESPATENT OFFICE 1 Claim.

This invention relates to cable terminal connections, and moreparticularly to cable terminal connections used with storage batteries,the primary object of the invention being to provide a terminalconnection having yieldable means which will cause the terminal tosecurely grip a battery post, eliminating the use of bolts and nutscommonly used in securing cable terminals to battery posts.

An important object of the invention is to provide a cable terminal ofthis character having overlapping ends, the overlapping ends being soconstructed that they will completely encircle the battery post withwhich the terminal is used, and one wherein the contacting surfaces ofthe terminal will be forced into close engagement with each other whenthe terminal is positioned on the battery post, thereby insuring a truecontact at all times.

With the foregoing and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein described, may be made within thescope of what is claimed, without departing from the spirit of theinvention.

Referring to the drawing:

Figure 1 is an elevational view illustrating a battery cable terminalpositioned over a battery post.

Figure 2 is a plan view thereof.

Figure 3 is a bottom view of the cable terminal connection prior to thepositioning of the cable terminal connection on a battery post.

Figure 4 is a sectional view taken on line 4-4 of Figure 2.

Figure 5 is an end elevatlonal view of the battery cable terminalconnection.

Referring to the drawing in detail, the cable terminal connection isindicated generally by the reference character 5, the connection beingconstructed of a composition of lead and Babbitt metal, commonlyemployed in cable terminal connection construction.

As shown, the cable terminal connection includes a substantiallycircular portion 6 split to provide overlapping ends 1 and 8. Theseoverlapping portions 1 and 8 are so tapered that when the connection isfitted over a battery post, which in the present showing is indicated bythe reference character 9, the overlapping portions will be forced intoclose engagement with each other,

providing a close fit, and insuring a true contact at all times. Thisconstruction also eliminates recesses and pockets usually found in cableterminal connection construction, and in which foreign matter due tocorrosion, usually collects. 5

Embedded in the substantially circular portion 6 of the cable terminalconnection, is a steel spring member I0 which is substantially wide andof a length so that the ends thereof will overlap and separate theoverlapping ends 1 and 8 of the 10 substantially circular portion 6,when the cable terminal connection is disconnected from a battery post,or out of use.

Thus it will be seen that due to this construction, the overlapping endsI and 8, will be 5 brought into close engagement with each other, whenthe cable terminal connection is forced downwardly over a battery post,as shown by the drawing.

When it is desired to position a cable terminal 20 connection, it isonly necessary to position the cable terminal connection over thebattery post and twist the cable terminal connection slightly to theright or left, at the same time pressing downwardly on the cableterminal connection. 5 To remove the device, the cable terminalconnection is moved slightly to the right or left, and slightly lifted.

The reference character I I indicates an extension which is formed witha socket to receive the 30 cable i2. This extension is also providedwith a cut-out portion so that portions of the extension may be forcedinwardly to closely grip the cable II. It may be desired to secure thecable within the socket by running solder or the like material 35 in thecut-out portion, as shown by'Figures 3 and 4 of the drawing.

Having thus described the invention, what is claimed is:

A battery connection comprising a body por- 40 tion constructed ofyieldable conductive material, said body portion including a split ringsection, the ends of the split ring section being held in overlappedengagement with each other and tapered to fine feather-like ends, aspring mem- 45 ber embedded in the split ring section and extending topoints adjacent to the ends of the split ring section the ends of thespring member overlapping and adaptedto urge the overlapping sections ofthe split ring section inwardly, and said split ring section adapted tobe positioned over a battery terminal, securely gripping the batteryterminal.
